The robotic spacecraft unravels the history of the our galaxy's evolution - and could identify habitable regions of the Milky Way
Astronomers have unveiled the most detailed survey of the Milky Way, revealing thousands of starquakes" and stellar DNA, and helping to identify the most habitable corners of our home galaxy.
The observations from the European Space Agency's Gaia probe cover almost two billion stars - about 1% of the total number in the galaxy - and are allowing astronomers to reconstruct our home galaxy's structure and find out how it has evolved over billions of years.
